Actually I find your delineation, quite satisfying an explanation.

However it begs one to ask what good is an impoverished measure of intelligence (IQ) that only computes your ability to recognize and exploit novel patterns, generalized across different domains (word problems, pictures, music), under time pressure if it doesn't so much as envelope the simple ability of a person to observe and verify that certain beliefs he or she holds subscribes to aren't causally attached to the rest of his or her experience

Isn't that simple enough a mental exercise?

Indeed, isn't that also a similarly intelligent exercise that constitutes the ability to recognize consistent patterns of denials and refusals in one's unremitting adherence to a religious faith?

What good is to ascribe intelligence (as in high IQ) to a person if the measure of intelligence is so narrowly defined?

I am left wanting for an explanation as to why the large majority of experts would concoct such an useless gauge of intelligence.

For the sake of pedagogy, instrumental rationality, I am certain, is a very fulfilling piece of terminology. I am also quite certain it is composed of attributes that are not necessarily equivalent to those of intelligence.

However if instrumental rationality is a skill than is not bestowed to you at birth unlike intelligence (from what I derive from your You can't learn to be more intelligent line) then what - in its thinnest scope - does intelligence constitute ?

Although I am not all that perturbed by it, this jargon of instrumental rationality and its neat separation from intelligence seems to have been contrived by theologians in a divinity school somewhere so as to not hurt the sentiments of the religious devotees.

I wouldn't be one bit surprised if also the various contrivances of intelligence - spatial, kinesthetic, rhythmic, linguistic, naturalistic, existential, mathematical, intrapersonal and interpersonal - are also more inventions of convenience than clearly circumscribed goods or measurable quantities.
